JetBlue will allow up to seven people to pool points. It’s open to domestic partners and people who aren’t relatives. Each pooling account needs at least one adult and can include up to five people younger than 21.

JetBlue executive Dave Canty said the change will appeal to families, friends, or groups of students who might not fly often enough individually to earn free trips.

Some were underwhelmed.

‘‘JetBlue has a generally weak loyalty program,’’ said FrequentFlier.com’s editor, Tim Winship. ‘‘The addition of a family-pooling feature makes it a bit more attractive, but only to a small segment of the traveling public.’’
